I've been holding off and holding off on joining up at Gearslutz, trying to come up with every possible reason why I shouldn't, but in the end I had to fold and submit, and this is the thread that did it.
So I'll say "hi" to some of the posters on this thread who know me from John Sayers' forum! (Brian, you finally forced me to register! It's all your fault!
). But after reading the technical depth of the discussion on this thread, I reckon I'll just be taking a back seat here, and going back to doing what I do best, and what I enjoy most: continuing to learn about acoustics from the Grand Masters that I hold in very high esteem, and admire greatly, such as Rod, Andre, John, Glenn, and some others.
Anyway, this is quite a thread, and quite an interesting outcome! I'd still love to see the full data, though.
And I have one question to add to the mix: How much does this paint cost? What was the estimated cost of the amount of paint that was used in those new tests, to get the marginal increase in the high-mid range?
I mean, the product might well work as depicted, but is it any cheaper than adding another layer of drywall, or (gasp!) a sheet of MLV? It seems to me that those would both provide a much greater increase in STC rating than this paint, and across a larger part of the spectrum too, so unless the paint is significantly less expensive per application than those (including labor), then I'm not sure that there is much of a point to it (except maybe where there just isn't enough space to add more drywall).
Anyway, just my 0.02.
